Risk of unfavorable outcomes after penile prosthesis implantation - results from a national registry (INSIST-ED)

Like all surgeries, penile prosthesis implantation (PPI) has the potential for both postoperative complications and suboptimal patient satisfaction. In order to assess risk factors for poor satisfaction, we reviewed patients who had been prospectively recruited in a national multi-institutional registry of penile prostheses procedures (INSIST-ED) from 2014 to 20121. Patient baseline characteristics and postoperative complications were recorded. The primary endpoint of this study was unfavorable outcomes after inflatable PPI, defined as significant postoperative complications (Clavien-Dindo ≥2) and/or Sexuality with Quality of Life and Sexuality with Penile Prosthesis (QoLSPP) scores below the 10th percentile. A total of 256 patients were included in the study. The median age was 60 years (IQR 56-67). The most common cause of erectile dysfunction (ED) was organic (42.2%), followed by pelvic surgery/radiotherapy (39.8%) and Peyronie's disease (18.0%). Postoperative complications were recorded in 9.6%. High-grade complications (Clavien ≥2) occurred in 4.7%. At 1-year follow-up, the median QoLSPP total score was 71 (IQR 65-76). In all, 14.8% of patients were classified as having experienced unfavorable outcomes because of significant postoperative complications and/or QoLSPP scores below the 10th percentile. Logistic regression analysis demonstrated patient age to be non-linearly associated with the risk of experiencing unfavorable outcomes. A U-shaped correlation showed a lower risk for younger and older patients and a higher risk for middle-aged men. ED etiology and surgical volume were not associated with PPI outcomes. Physicians should, therefore, be aware that middle-aged men may be at higher risk of being unsatisfied following PPI compared to both younger and older patients.

C75 PHEOCHROMOCYTOMA–INDUCED CARDIOGENIC SHOCK: A MULTICENTER ANALYSIS OF CLINICAL PROFILES, MANAGEMENT AND OUTCOMES

Background

Pheochromocytoma is a rare neuroendocrine tumor that arises from the adrenal gland and overproduces catecholamines; it is an infrequent cause of cardiogenic shock (CS). Several case reports have investigated pheochromocytoma–induced CS, but larger studies have not yet been carried out.

Objectives

Our work aims to describe a multicenter experience in the diagnosis and management of patients with pheochromocytoma–induced CS, and to raise awareness around this rare condition. Methods: We enrolled all patients with a diagnosis of pheochromocytoma–induced CS admitted to the intensive care units of 8 European referral Hospitals.

Results

Among the 17 patients (47% males, mean age 49,5 years), we found that pulmonary congestion was the mostly represented clinical feature (82%). The most represented echocardiographic left ventricle (LV) pattern was the reverse Takotsubo (TTS) pattern with apical hyperkinesis associated with basal– to mid–ventricular hypokinesis (47%). Elevated systemic vascular resistances (SVR) were observed. Endomyocardial biopsy of the LV was performed in one patient showing contraction band necrosis, oedema and inflammatory reaction. 76% of patients were treated with dobutamine, 70% needed noradrenaline, 29% adrenaline, 23.5% were treated with levosimendan and 17% with milrinone. Mechanical circulatory support devices (MCS) were necessary for 65% of patients. All patients benefited from pheochromocytoma’s surgical excision, with 4 patients operated on while under ECLS. All patients recovered, excepted one (presenting a severe left ventricular dilatation at admission) who required cardiac transplantation.

Conclusion

Pheochromocytoma is an infrequent cause of CS, with most often a TTS–like presentation. It should be suspected in case of a CS with high initial SVR and rapid deterioration. MCS must be considered in the most severe cases. The main challenge is to stabilize the patient, mostly with MCS, since it remains a reversible cause of CS with a low mortality rate. Adrenalectomy can safely be performed even when the patient is under MCS.

Italian experiences in the management of andrological patients at the time of Coronavirus pandemic

The SARS-CoV-2 (Severe acute respiratory syndrome coronavirus 2) was first reported in December 2019, then its rapid spread around the world caused a global pandemic in March 2020 recording a high death rate. The epicenter of the victims moved from Asia to Europe and then to the United States. In this Pandemic, the different governance mechanisms adopted by local health regional authorities made the difference in terms of contagiousness and mortality together with a community strong solidarity. This document analyzes the andrological urgencies management in public hospitals and in private practice observed in Italy and in particular in the most affected Italian Regions: Emilia-Romagna and Marche.

Simultaneous curvature correction at the time of the penile fracture repair: surgical and functional outcomes

Purpose: After a penile fracture (PF), an early surgical exploration and defect closure of the lesions are recommended to prevent long-term complications. However, postoperative unsatisfactory penile curvatures are frequent in the literature. In this study, we wished to present surgical outcomes of PF after surgical repair approach with an early intraoperative curvature correction and update our series with postoperative follow-up.

Patients and methods: An institutional retrospective review study of 36 patients undergoing surgical treatment for PF was performed. Mean age of patients was 53.2 years. All surgical explorations were performed within 12 hours after the traumatic event. The surgical repair with a contemporary penile plication was then made to straighten the tunica angulations in patients with curvature greater than 30°, using 2– 3 pairs of 2–0 absorbable suture of polydioxanone.

Results: The length of the tear ranged from 8 to 20 mm. 77.7% of the patients required a correction of the cavernous body deviation. No early complications occurred in any case. The median patient stays in the hospital was 3.4 days. At a mean follow-up of 20.6 months, all patients were able to insert the penis in the partner’s vagina, and were satisfied overall with sexual intercourse; three patients (10.7%) reported residual pain and discomfort for the knots of the sutures.

Conclusions: An early intraoperative curvature correction may be used for a variety of angulation deformities and severe degrees of deviations secondary to a repair after penile trauma, and may be helpful in preventing postoperative morbidity.

Approach for Renal Tumors With Low Nephrometry Score Through Unclamped Sutureless Laparoscopic Enucleation Technique: Functional and Oncologic Outcomes

PURPOSE

We report an unclamped sutureless laparoscopic simple enucleation (LSE) technique for renal tumors with low nephrometry score and analyze complication rates as well as functional and oncologic outcomes.

PATIENTS AND METHODS

We reviewed the data of 143 consecutive patients who underwent sutureless laparoscopic tumor enucleation with zero ischemia by a single experienced laparoscopic surgeon. The inclusion criteria for LSE with zero ischemia were tumor size ≤ 5 cm and RENAL nephrometry score of 4 to 6. The following data were collected: age, gender, body mass index, tumor side, renal function, tumor characteristics, American Society of Anesthesiologists score, operative time, positive surgical margins, estimated blood loss, and surgical complications.

RESULTS

The median RENAL score of patients was 4.7. Median tumor size was 2.7 cm. Conversion to open surgery and hilum vessels clamped were not necessary in any patient. There were no changes in postoperative creatinine values and estimated glomerular filtration rate. The median operation duration time was 78.2 minutes, and median estimated blood loss was 110.2 mL. The median hospital stay was 3.8 days. A total of 2.8% of the patients had positive surgical margins at pathologic examination. Of the 143 patients, 7% developed fever after surgery requiring an adequate antibiotic regimen, 1.4% developed postoperative bleeding requiring blood transfusions, and 0.7% had postoperative urinary leakage from the drainage requiring double-J stent position.

CONCLUSION

The unclamped sutureless LSE is a rational and safe approach to renal tumors with a low nephrometry score. This surgical technique does not increase the complication rate despite the reduction in parenchymal mass excised and the absence of hilar control.

Pseudoaneurysm with arteriovenous fistula of the prostate after pelvic trauma: Ultrasound imaging

Pseudoaneurysm (PA) associated with an arteriovenous fistula (AVF) of the internal pudendal artery branches are very uncommon. We report a case of post-traumatic PA with AVF connected to Santorini plexus. Diagnosis was made with trans-rectal ultrasound (TRUS) after recurrent hematuria. TRUS reported a 1.7 × 1.4 × 1.5 cm anechoic area, on anterior prostate apex close to Santorini plexus. The use of color Doppler in this area revealed high flow velocity that was indicative for AVF. The feeding artery was a distal branch of the left pudenda artery. After selective embolization was observed complete occlusion of the feeding branches and disappearance of PA with AVF. Prostate PA with concomitant symptomatic AVF detected with TRUS has not yet described in literature after pelvic trauma and represents complex diagnostic challenges. This case report suggests that the use of TURS and color Doppler can provide an important diagnostic and follow-up to address the clinical suspicion of occult vascular injuries using a noninvasive approach.

Testicular prosthesis: Patient satisfaction and sexual dysfunctions in testis cancer survivors

Purpose: We studied patient satisfaction about sexual activity after prosthesis implantation using validated questionnaires with the aim to discover if testicular prosthesis could be responsible of sexual dysfunctions (erectile dysfunction or premature ejaculation). Materials and Methods: We evaluated a total of 67 men who underwent radical orchiectomy for testicular cancer and a silicon testicular prosthesis implantation from January 2008 to June 2014 at our Hospital. These patients completed 5 validated questionnaires the day before orchiectomy and 6 months after surgery: the International Index of Erectile Function 5 (IIEF5), the Premature Ejaculation Diagnostic Tool (PEDT), the Body Exposure during Sexual Activities Questionnaire (BESAQ), the Body-Esteem Scale and the Rosenberg Self- Esteem Scale. We also evaluated 6 months after surgery any defects of the prosthesis complained by the patients. Results: The questionnaires completed by patients didn’t show statistically significant changes for erectile dysfunction (p > 0.05) and premature ejaculation (p > 0.05). On the contrary the psychological questionnaires showed statistically significant change for the BESAQ (p < 0.001) and the Body Esteem Scale (p < 0.001), but not for the Rosenberg Self-Esteem Scale (p > 0,05). A total of 15 patients (22.37%) were dissatisfied about the prosthesis: the most frequent complaint (8 patients; 11.94%) was that the prosthesis was firmer than the normal testis. Conclusions: Testicular prosthesis implantation is a safe surgical procedure that should be always proposed before orchiectomy for cancer of the testis. The defects complained by patients with testicular prosthesis are few, they don’t influence sexual activity and they aren’t able to cause erectile dysfunction or premature ejaculation.

INSIST-ED: Italian Society of Andrology registry on penile prosthesis surgery. First data analysis

OBJECTIVES

The Italian Society of Andrology, i.e. "Società Italiana di Andrologia" (S.I.A.), launched on December 2014 a prospective, multicenter, monitored and internal review board approved Registry for penile implants, the "INSIST-ED" (Italian Nationwide Systematic Inventarisation of Surgical Treatment for ED) Registry. Purpose of this first report is to present a baseline data analysis of the characteristics of penile implant surgery in Italy.

MATERIAL AND METHODS

The INSIST-ED Registry is open to all surgeons implanting penile prostheses (all brands, all models) in Italy, providing anonymous patient, device, surgical procedure, outcome, follow-up data, for both first and revision surgeries. A Registry project Board overviews all the steps of the project, and a Registry Monitor interacts with the Registry implanting surgeons.

RESULTS

As by April 8, 2016, 31 implanting surgeons actively joined the Registry, entering 367 surgical procedures in its database, that comprise: 310 first implants, 43 prosthesis substitutions, 14 device explants without substitution. Implanted devices account for: 288 three-component devices (81,3%), 20 two-component devices (5,4%), 45 non-hydraulic devices (12,3%). Leading primary ED etiologies in first implant surgeries resulted: former radical pelvic surgery in 111 cases (35,8%), Peyronie's disease in 66 cases (21,3%), diabetes in 39 cases (12,6%). Two intraoperative complications have been recorded. Main reasons for 57 revision surgeries were: device failure (52,6%), erosion (19,3%), infection (12,3%), patient dissatisfaction (10,5%). Surgical settings for patients undergoing a first penile implant were: public hospitals in 251 cases (81%), private environments in 59 cases (19%).

CONCLUSIONS

The INSIST-ED Registry represents the first European experience of penile prosthesis Registry. This baseline data analysis shows that: three-pieces inflatable prosthesis is the most implanted device, leading etiology of erectile dysfunction (ED) in patient receiving a prosthesis is former radical pelvic surgery, primary reason for revision surgery is device failure, primary settings for first penile implant surgery are public hospitals. Evaluation of penile implant impact on recipients quality of life is presently ongoing.

Insulin/glucose induces natriuretic peptide clearance receptor in human adipocytes: a metabolic link with the cardiac natriuretic pathway

Cardiac natriuretic peptides (NP) are involved in cardiorenal regulation and in lipolysis. The NP activity is largely dependent on the ratio between the signaling receptor NPRA and the clearance receptor NPRC. Lipolysis increases when NPRC is reduced by starving or very-low-calorie diet. On the contrary, insulin is an antilipolytic hormone that increases sodium retention, suggesting a possible functional link with NP. We examined the insulin-mediated regulation of NP receptors in differentiated human adipocytes and tested the association of NP receptor expression in visceral adipose tissue (VAT) with metabolic profiles of patients undergoing renal surgery. Differentiated human adipocytes from VAT and Simpson-Golabi-Behmel Syndrome (SGBS) adipocyte cell line were treated with insulin in the presence of high-glucose or low-glucose media to study NP receptors and insulin/glucose-regulated pathways. Fasting blood samples and VAT samples were taken from patients on the day of renal surgery. We observed a potent insulin-mediated and glucose-dependent upregulation of NPRC, through the phosphatidylinositol 3-kinase pathway, associated with lower lipolysis in differentiated adipocytes. No effect was observed on NPRA. Low-glucose medium, used to simulate in vivo starving conditions, hampered the insulin effect on NPRC through modulation of insulin/glucose-regulated pathways, allowing atrial natriuretic peptide to induce lipolysis and thermogenic genes. An expression ratio in favor of NPRC in adipose tissue was associated with higher fasting insulinemia, HOMA-IR, and atherogenic lipid levels. Insulin/glucose-dependent NPRC induction in adipocytes might be a key factor linking hyperinsulinemia, metabolic syndrome, and higher blood pressure by reducing NP effects on adipocytes.

Reassessing the role of subclinical varicocele in infertile men with impaired semen quality: a prospective study

OBJECTIVE

To evaluate the seminal, hormonal, and spontaneous pregnancy outcome after percutaneous embolization of the internal spermatic vein in infertile men with left-sided subclinical varicocele and one or more abnormal semen parameters.

METHODS

A total of 218 patients underwent percutaneous embolization, and 119 patients were included as the observation group. All patients were followed up prospectively for 39.4 ± 6.5 months. Semen parameters and hormonal levels were evaluated before any procedure and 6 months after.

RESULTS

Significant improvement in the mean sperm concentration, total motility, and lower follicle-stimulating hormone levels was noted in those who underwent varicocele embolization as compared with those not treated. After 39.4 ± 6.5 months, pregnancy rates were 46.3% for the treated group and 11.8% for the control group (P = .011).

CONCLUSION

In infertile men, small varicoceles, even subclinical ones, should be identified and treated.

Improvement of lower urinary tract symptoms and sexual activity after open simple prostatectomy: Prospective analysis of 50 cases

Objectives: To evaluate the improvement of Lower Urinary Tract Symptoms (LUTS) and Erectile Function (EF) evaluated before and after Open Simple Prostatectomy, focusing on which patients this procedure allows better outcomes in term of sexual activity. Material and methods: 50 men with large size benign prostatic hyperplasia (BHP) greater than 80 gr were prospectively evaluated before and 6 months after Open Simple Prostatectomy (Freyer procedure) between October 2012 to September 2013. Patients had a pre-operative transrectal ultrasound (TRUS) for volume evaluation and filled pre and post operative questionnaires for International Prostate Symptom Score (IPSS) and International Index of Erectile Function (IIEF-5) score. Results: Mean patients age was 71 years (D.S. 3,5), mean prostate volume results 103 ml (D.S. 23,7); regarding LUTS and EF, mean improvement of IPSS score was 15,3 (D.S. 4) and mean increase of IIEF-5 score was 3,4 (D.S.3). This study highlights a correlation between patients’ age and increase of IIEF-5 score; no correlation with prostate size was found. Conclusion: According to the EAU Guidelines 2014, large size BPH (over 80-100 mL) with LUTS refractory to medical management continue to have open prostatectomy as the treatment of choice. In our experience we found not only an reduction of LUTS after the procedure but also an improvement of erectile function; this improvement was related with patient’s age.

The impact of repeated prostate biopsies on sexual function and urinary symptoms in patients with diagnosis of Atypical Small Acinar Proliferation (ASAP): Can ecoDoppler reduce side effects?

Objectives: To establish whether repeated trans-rectal ultrasound-guided Prostate Needle Biopsies (PNBx) performed in men with diagnosis of Small Acinar Atypical Proliferation (ASAP) predispose these subjects to Erectile Dysfunction (ED) and to evaluate if EcoColorDoppler (ECD) can help to reduce this side effect. Materials and methods: We performed a retrospective study regarding 190 men with diagnosis of ASAP detected between January 2001 and December 2011, who underwent to repeated prostate needle biopsies (PNBx). These patients were investigated about Erectile Function (EF) and Lower Urinary tract Symptoms (LUTS) using International Index of Erectile Function (IIEF-5) and International Prostate Symptom Score (IPSS) questionnaires before the first PNBx and 3 months after each other one. In particular, among the 89 men without ED before first PNBx, we compared IIEF-5 score between 64 patients who underwent to standard PNBx and 25 patients submitted to a PNBx done with in addition ECD ultrasound imaging. Results: Mean patient age was 65 years (SD 7.7); mean follow-up was 3.2 years (SD 1.8) and the mean number of re-biopsies completed was 2 (SD 1.5). Among the 143 men considered, only 89 resulted with a normal EF (IIEF-5 score > 21): in this group incidence of ED (IIEF-5 score < 21) among patients who underwent to standard PNBx was 4/64 (6.25%) while in patients submitted to a PNBx with ECD was 1/25 (4%). A greater decrease of EF was observed in patients undergone to 3 or more biopsies; no relationship between IPSS score and re-PNBx was identified. Conclusion: Repeated PNBx done in patients with diagnosis of ASAP appear to get worse EF; number of biopsies seems to increase the risk of ED. Use of ECD in transrectal ultrasound- guided PNBx may have a role to avoid neurovascular bundles (NVBs) and preserve EF; anyway further studies are highly recommended to validate this hypothesis.

Percentage change of FSH value: new variable to predict the seminal outcome after varicocelectomy

In the literature, there is no good agreement with variables to predict seminal outcome after varicocelectomy. The purpose of this study was to evaluate the FSH percentage change (Δ% FSH) as a predictor of the seminal outcome after varicocelectomy together with other known predictors. We evaluated 118 patients who underwent varicocelectomy. We assessed factors that could be predictors of the improvement of semen characteristics: LH, FSH, total and free testosterone before operation, testis volume, age, testicular pain, body mass index (BMI), Δ% FSH, varicocele Doppler ultrasound grade using regression analysis. Mean sperm concentration increased from 27 ± 12 to 52 ± 15 million per ml post-operatively (P < 0.003), mean sperm motility increased from 31 ± 12 to 40 ± 13 million per ml following the operation (P < 0.02), also mean FSH value changed from 10.2 ± 8.3 to 6.7 ± 7.2 UI/L (P < 0.01). In unvaried regression analysis, Δ% FSH, BMI and age were predictors of the improvement of semen characteristics. In multiple regression analysis, only Δ% FSH and age were predictors. Negative correlation with age and positive correlation with Δ% FSH were observed. Our findings suggest that Δ% FSH (before and after varicocelectomy) and age are significant factors predicting the improvement of semen characteristics.

Testicular microlithiasis and dyspermia: Is there any correlation?

Background: Testicular microlithiasis (MT) is an uncommon sonographic finding (prevalence in the literature: 0.7 to 6%). Several studies have highlighted its possible correlation with an increased risk of testicular cancer, but few studies have investigated its possible link with dyspermia. Objectives: The aim of our study was to investigate in our series the number of patients with microlithiasis, diagnosed by ultrasound, and compare the quality of their sperm with that of patients in a control group with normal testicular ultrasound exam. Materials and methods: We performed 277 consecutive testicular ultrasound examinations from January 2012 to July 2012. Among all these, we selected 86 patients that showed no pathological elements at echography and 11 patients affected by MT, to one or both testicles. Each patient was also submitted to a short-term semen analysis using the WHO2010 parameters for sperm evaluation. Results: Among 11 patients with MT, 7 (63.63%) were dyspermic and 4 (36.36%) were normospermic. Among the 86 patients with normal testicular ultrasound 51 (59.3%) were dyspermic, 4 (4.65%) were azoospermic, while the remaining 31 (36.05%) were normospermic. Comparing the results of the two groups we obtained an odds ratio of 0.99 (95% CI: 0.27 to 3.64, p: 0.98). Conclusions: This study, although preliminary, with a low number of partecipants, shows that sperm quality is not affected by the presence of testicular microlithiasis, because the results of spermiograms are almost comparable between the two groups.

Comparison between WHO (World Health Organization) 2010 and WHO 1999 parameters for semen analysis – interpretation of 529 consecutive samples

Objective: To quantify how many men with normal semen according to WHO (WHO - World Health Organization) 1999 criteria, should be considered with abnormal semen according to 2010 criteria and vice versa; to study which parameter of volume, concentration, motility and morphology is the most responsible of this change. Materials and methods: We studied, using WHO 1999 parameters, 529 consecutive semen samples from 427 men, collected in our Department from January 2008 to December 2009, then we re-evaluated those results using WHO 2010 parameters; we also studied each parameter to understand how changed the classification from normal (defined normal by all parameters) to abnormal (defined abnormal by at least one parameter) using the two WHO criteria. Results: 3 men (0.56%) were azoospermic. Among the remaining 526 samples, 199 (37.83%) were considered normal and 246 (46.76%) abnormal both according to WHO 1999 and WHO 2010 criteria; we found that none of the samples classified normal according to the previous criteria was classified abnormal according the more recent criteria, while 82 (15.58%) evaluated as abnormal according 1999 criteria changed to normal according 2010 criteria. The concordance between 1999 and 2010 evaluation was 84.44%. Conclusions: In this study we noted that the changes from WHO 1999 to WHO 2010 criteria did not modify the interpretation of semen quality, because comparing the two classifications we demonstrated that there is a substantial agreement, considering the three parameters (count, motility and morphology) all together, and also considering each single parameter. Anyhow, almost 16% of the patients considered infertile according to the old criteria, should be evaluated normal by the new classification and they should not need any treatment for infertility.

Comparison of tamsulosin vs tamsulosin/sildenafil effectiveness in the treatment of erectile dysfunction in patients affected by type III chronic prostatitis

AIM

We evaluated the effectiveness of tamsulosin monotherapy versus tamsulosin plus sildenafil combination therapy on erectile dysfunction (ED) in young patients with type III chronic prostatitis and ED by using symptom score scales.

MATERIALS AND METHODS

44 male patients were divided into 2 groups: the first group (20 patients) was treated with tamsulosin 0,4 mg monotherapy and the second one 24 patients) was treated with tamsulosin 0,4 mg plus sildenafil 50 mg combination therapy. “International Prostate Symptom Score, “National Institute of Health Chronic Prostatitis Symptom Index" (NIH-CPSI) and “International Index of Erectile Function" (IIEF-5) were investigated in each group of patients, and scores calculated during the first medical examination. Both groups were treated with tamsulosin once daily for 60 days, while sildenafil 50 mg was given on demand (at least 2 times per week) for 60 days. During the second medical examination IPSS, NIH-CPSI and IIEF-5 scores were analyzed once more. Afterwards, the alterations of scores among medical examinations in each group and between both groups were statistically compared.

RESULTS

The age average of the 44 cases included was 32.04 3.15 years. Both groups present a statistically significant decrease, between the first and the second medical examination, in IPSS, NIH-CPSI scores and statistically significant increase in IIEF-5 score. In addition, there is no statistically significant difference, in all scores, between mono and combination therapy.

CONCLUSIONS

tamsulosin monotherapy, as well as a combination therapy (tamsulosin plus sildenafil) has an improving effect on symptoms and on ED in patients with type III prostatitis. In the near future alpha-blockers monotherapy could be used in the treatment of chronic prostatitis and ED cases instead of phosphodiesterase type 5 (PDE-5) inhibitors combination therapy.

Do DNA-methylation and histone acetylation play a role in clear cell renal carcinoma? Analysis of radical nephrectomy specimens in a long-term follow-up

We investigated global methylation and histone acetylation in 50 conventional clear cell renal carcinomas (RCC), treated with radical nephrectomy, to assess their possible role as diagnostic biomarkers. The features considered in this study were patient age, tumor size and grade, percentage and intensity of 5-methylcytosine (5mc) and Acetyl-Histone (Lys 9) expression in tumor tissue. All considered parameters were correlated with patient specific survival. The mean percentage of global cellular methylation in tumoral tissue was significantly higher compared to normal peritumoral tissue (p<0.0001), while the intensity of cellular methylation was significantly higher in normal tissue than in tumoral tissue (p=0.001). The mean percentage of histone cellular acetylation in tumoral tissue was significantly lower compared to normal peritumoral tissue (p=0.0005), while the intensity of mean acetylation in neoplastic tissue was similar to the normal tissue. The percentage of global DNA methylation was significantly higher in grades 3 and 4 tumors (p=0.033). Global DNA methylation and histone acetylation in tumoral tissue did not correlate with survival. Fuhrman grade was statistically significant for prognosis (p=0.031). In conclusion, global hypermethylation and histone hypoacetylation play an important role in RCC carcinogenesis; Fuhrman grade is still considered the most important factor for patient survival; 5mc can have a role as markers of aggressiveness.

Testicular Cancer. Open Questions: Prevention, Early Diagnosis and Infertility

Testicular cancer is the most common malignancy in men aged 15–35 years. Histologically testicular germ-cell tumors have two main subtypes: pure seminoma and non-seminoma. Knowing the histopathological tumor type and detecting the relevant prognostic factors helps to guide the subsequent therapeutic course.

At present there are no recommendations for testicular cancer screening in healthy young men, even among men showing high risk; however, a testicular cancer should be diagnosed as soon as a young man presents with suggestive signs and symptoms. Furthermore, thanks to highly effective treatments including surgery, chemotherapy, and radiation therapy, it is very important to effectively manage secondary prevention and improve these patients’ quality of life. Secondary prevention of relapses or secondary malignancy onsets should be carried out through a regular follow-up of the patient; in selected cases of positive family history, it is possible to perform genome-wide analyses aiming at searching the genes possibly causing testicular germ-cell tumor in affected first-degree male relatives. Long-term therapies can yield infertility and sexual dysfunction, issues gaining more and more importance from a clinical point of view.

Sperm cryopreservation should be systematically offered to all requiring patients; moreover, screening for gonadal dysfunction should be considered in the follow-up of testicular cancer survivors, with the aim of hormone supplementation in symptomatic patients. (Urologia 2007; 74: 8–14)

Magnetic resonance imaging of posterior cruciate ligament injuries: a new classification of traumatic tears

PURPOSE

The aim of our study was to propose a new classification of acute posterior ligament (PCL) injuries based on magnetic resonance imaging (MRI).

MATERIALS AND METHODS

Using MRI, we reviewed 220 patients presenting an acute posterior ligament injury. The MRI exam was performed on a 0.2-Tesla (T) magnet and a 1.5-T magnet using T1-weighted spin echo (SE), T2-weighted SE and fat-suppression scans [short-tau inversion recovery (STIR)] in axial, sagittal and coronal planes. In no case was paramagnetic contrast agent injected.

RESULTS

Twenty-five per cent of patients were identified as having type I lesions and another 30% as having type II lesions according to the Gross classification. Out of 77 patients, 35% of the whole sample, 37 had a tear of the posteromedial fascicle (type II lesion), and the remaining 40 had anterolateral fascicle tears (type III). In 10% of cases, the ligaments appeared completely interrupted, and these were classified as type IV lesions.

CONCLUSIONS

T1-weighted SE sequences need to be integrated with T2-weighted and STIR sequences to detect the real extent of the remaining fascicle. The MRI exam could thus be able to provide a qualitative evaluation of PCL injuries and establish how the injury compromises joint stability.

Hematospermia: diagnosis and treatment

The presence of blood in ejaculate represents 1% of all andrologic and urologic symptoms. In most cases it has a benign character and tends to regress spontaneously after the first episode. But in the same case it can be caused by bladder-prostate or systemic malignant patology, so it is necessary to subject the patient to laboratory and instrumental tests in order to find the best treatment that, as for hematospermia, is an etiological one. Most important for correct diagnosis are patient history, physical examination, laboratory tests, transrectal ultrasound examination of the prostate, MRI, CT, cistoscopy. Hematospermia is rarely associated with significant pathology, especially in younger men. The 3 factors that dictate the extent of the evaluation and treatment are patients age, the duration and recurrence of the hematospermia, and the presence of any associated hematuria. So it is possible to distinguish idiopathic from secondary hematospermia, because secondary hematospermia, i.e. the one in which the bleeding cause is known or suspected, requires an etiologic treatment. Urologists must make rational decisions based on evidence rather than practice defensive medicine. Understanding the pathophysiology and prevalence in populations of different ages helps minimize the likelihood of problems. When in doubt, performing a TRUS, cystoscopy, and basic laboratory analyses limits exposure.

Leucocytospermia: Which Relationship with Male Infertility?

Leucocytospermia is usually associated with genito-urinary tract infections and its role on male infertility is currently under debate. The aim of this study was to investigate the relationship between leucocytospermia and seminal fluid alterations in men with fertility problems. We evaluated 40 consecutive spemiograms of leucocystospermic men, and another 40 from individuals without leucocytospermia, with regard to age, number, motility and sperm morphology, and presence of genito-urinary tract infections. There was a significant difference in terms of motility (23.27% in non-leucocytospermic pts vs. 15.57% in leucocytospermic pts., p=0.0034). Furthermore, asthenozoospermia was more frequent in leucocytospermic pts (45% vs. 72.,%, p=0.0231), as also teratozoospermia (32.5% vs. 62.5%, p=0.0138). The probability to have at least one of the major seminal alterations was greater in leucocytospermic pts (75.3% vs. 52.5%, p=0.0048). The incidence of infections in leucocytospermic group was 13%. Our study underlines the relationship between leucocytospermia, motility, and normal morphology reduction in human semen. These data might suggest the presence of a damage due to the ROS produced by seminal leucocytes on spermatozoa. Our analysis wants to emphasize the need to treat this condition, with special regard to the frequent use of PMA procedures.

An Evaluation of Quality of Life in Patients who Underwent Urinary Diversion after Radical Cistectomy: Comparison of Different Urinary Diversions, our Experience

The aim of the study was to compare health-related quality of life (HRQOL) in 3 groups of patients with different urinary diversions using the “36 Item Short-Form Healt Survey” questionnaire; metabolic changes related to urinary diversion were also evaluated. The study included 22 patients who underwent radical cystectomy for bladder cancer: 10 pts had an an ileal-conduit (Group I), 9 had a retto-sigmoid pouch sec. Mainz II (Group II), and 3 had an ileal orthotopic neobladder (Group III).

There were no significant differences among the 3 groups regarding the metabolic status. The SF -36 survey showed that patients with ileal-conduit (Group I) had a significant decrease of general health (GH) and of physical functioning (AF) scores compared to patients with continent urinary diversion (Groups II and III). This appeared to be related to a decreased emotional drive (RE) rather than to a loss of vitality (VT).

There were no significant differences in any scale score between Group II and III.

Cardiovascular effects of sildenafil in hypertensive men with erectile dysfunction and different alleles of the type 5 cGMP-specific phosphodiesterase (PDE5)

Erectile dysfunction (ED) is frequent in patients with essential hypertension (EH); a likely common pathogenetic pathway could be a reduced ability of arteriolar vascular smooth muscle (VSM) to relax. Increasing intracellular levels of cGMP reduce the contractile status of VSM; on the contrary, type 5 cGMP-specific phosphodiesterase (PDE5, codified by PDE5A gene) regulates cGMP levels through its clearance. The PDE5A gene represents a good candidate for the intermediate phenotype EH/ED: genetic variants of the PDE5A may predispose to EH and ED and could affect the local and systemic response to sildenafil administration. Thus, a functionally relevant portion of PDE5 5'-flanking promoter region was analyzed by PCR and direct sequencing in patients with EH and idiopathic ED. The sequences obtained showed a T/G polymorphism at position -1142, near an AP1 regulatory element, that was not apparently associated with the intermediate phenotype. We also studied the relationship between this polymorphism and the effects of oral sildenafil on blood pressure (BP) and heart rate (HR) in men with ED. Sildenafil caused a significant decrease of BP, but had no effects on HR; statistical analysis showed no differences in BP and HR variations among PDE5A genotypes. In conclusion, our data showed no correlations of a novel polymorphism of the PDE5A promoter gene with the intermediate phenotype EH/ED and the BP and HR response to sildenafil administration. Further studies are necessary to define the role of this polymorphism and to study the genetic predisposition for EH with ED.

Transurethral resection versus minimally invasive treatments of benign prostatic hyperplasia: results of treatments. Our experience

OBJECTIVE

In this non-randomized prospective study the results of standard TURP (Transurethral Resection of the Prostate) versus other minimally invasive treatments were compared.

MATERIALS AND METHODS

Among all the patients treated at our Institution for bladder outlet obstruction due to BPH (Benign Prostatic Hyperplasia) from January 1995 to June 1998, 212 patients have been evaluated; 90 patients underwent to TURP, 13 patients to TVP (Transurethral ElectroVaporization), 24 patients to TUNA (TransUrethral Needle Ablation), 71 patients to ILC (Interstitial Laser Coagulation), and 13 patients to WIT (Water-Induced Thermotherapy).

RESULTS

TURP achieves the highest decrease of prostate volume (48.8%), the best increase of maximum flow rate (75.3%) and the highest decrease of residual volume (89.8%) in comparison to other methods; these results are substantially stable 24 months after treatment; on the other hand, after WIT a reduction of prostatic volume of 5.2%, an increase of maximum flow rate of 16.7% and a decrease of residual volume of 25.2% can be observed. The relief of bladder outlet obstruction is indicated by the decrease of detrusor pressure at maximum flow rate in comparison to baseline values; it decreases of 27.5% for WIT, of 34.8% for TUNA, of 38.3% for ILC, of 48.4% for TUR, and of 53.3% for T.P The recorded results are substantially stable 24 months after treatment. A marked decrease of IPSS and QL score can be observed for all the procedures after 6 months, ranging from 40.2% for WIT to 76.7% for TUNA; however, these parameters undergo to a slight worsening 24 months after treatment for TURP, TVP and TUNA, while remain substantially stable for ILC and WIT.

CONCLUSION

From the analysis of our results, it appears that TURP is still the golden standard treatment for BPH; TURP remains the most effective and definitive way of treatment, but it could be less attractive from the patients' perspective, especially after minimally invasive treatments with good tolerability have become available. It is therefore evident that the choice of each method should be performed in consideration of patients' general performance status, of symptoms and of indications and contraindications of each method.

Percutaneous Therapy of Varicocele: Effects on Semen Parameters in Young Adults

BACKGROUND

In spite of many years of debate, the impact of varicocele on male infertility is still controversial since its pathogenetic role on the impairment of semen quality has never been fully demonstrated.

METHODS

In the present work, a series of 426 young adult males undergoing percutaneous treatment of varicocele were studied and semen parameters were evaluated at baseline and 12 months of follow-up.

RESULTS

A significant increase in sperm cell concentration and a decrease in immotile spermatozoa were found after varicocele repair, but we failed to detect any significant positive change in progressive motility as well in sperm morphology after treatment. Similar results were also obtained when semen parameters were correlated with the degree of varicocele.

CONCLUSION

Since a spontaneous improvement in semen quality has been mathematically established as a model of regression toward the mean, we conclude that the correction of varicocele in young adults is not a major indication when semen alteration is the only clinical problem.

Sexual function in patients with LUTS suggestive of BPH

BACKGROUND

Sexual function has been detected in a large sample of Italian patients affected by LUTS suggestive of BPH, by means of the ICS-Sex questionnaire.

RESULTS

A number of 877 questionnaires were returned completely filled and were analyzed. Fifty percent of patients declared that their sexual life was significantly affected by their urinary symptoms. Difficulty in getting erections (58.2% of patients) and ejaculation problems (55.6%) were reported by the majority of patients, but the relevant bother was significantly different (48.3 and 33.4%, respectively). The ICS-Sex score was significantly associated with all the measures of symptoms and QoL employed in the study (IPSS and ICS-BPH). The urinary symptoms most frequently associated with sexual dysfunction were those related to incontinence.

CONCLUSIONS

The QUIBUS study shows that sexual dysfunctions are commonly complained of by Italian men with LUTS and are significantly associated with urinary symptoms, in particular with urine loss. These findings support the recommendation by the 5th International Consultation on BPH to better evaluate both sexual function and incontinence symptoms in patients affected by LUTS suggestive of BPH.

Diagnostic accuracy of percent free prostate-specific antigen in prostatic pathology and its usefulness in monitoring prostatic cancer patients

INTRODUCTION

The aim of our study was to evaluate the clinical usefulness of percent free prostate-specific antigen (PSA) [ratio of free PSA (fPSA) to total PSA (tPSA); f/tPSA] in prostatic pathology and its usefulness in monitoring prostatic cancer patients.

PATIENTS AND METHODS

Our prospective study was carried out on 470 consecutive male patients referred to our outpatient urological clinic for observation. We looked for relationships between tPSA, fPSA and percent free PSA and the patient's age, prostatic volume and histologic diagnosis as assessed by prostatic biopsies or surgical specimens (benign prostatic hypertrophy, carcinoma, hypertrophy with inflammation). In all cases, we calculated the specificity, sensitivity and diagnostic accuracy of percent free PSA in the diagnosis of prostatic diseases, using cutoff values ranging from 14 to 20%. In prostatic cancer patients, we considered the relationships between the various PSA molecular forms and staging, grading and follow-up values. We also evaluated the effects of hormonosuppressive therapy on the serum markers and noted for which tPSA value percent free PSA possessed the greatest diagnostic accuracy.

RESULTS

While tPSA and fPSA values appeared to be correlated with patient age and prostatic volume, percent free PSA did not show a relationship with these parameters. The specificity, sensitivity and overall diagnostic accuracy were better assuming a 16% cutoff value for percent free PSA than with other cutoff values. Prostatic inflammation associated with benign hypertrophy can cause false positives in both tPSA and f/tPSA measurements, since 60% of these patients have an f/tPSA ratio below 16%. In diagnosing carcinoma, the diagnostic accuracy of percent free PSA is 100% when tPSA is between 2.5 and 4.0 ng/ml. Percent free PSA is not linked with staging in prostatic cancer, but it does appear to be related to the Gleason score. In patients receiving hormonosuppressive treatment, f/tPSA decreased significantly, and more so in patients with a higher Gleason score. In patients with disease in rapid progression, percent free PSA was lower than in patients in a stable condition.

CONCLUSIONS

Based on our experience, 16% as the f/tPSA cutoff value for discriminating between benign and malignant pathologies is the best possible choice, as it provides the highest overall values of sensitivity, specificity and diagnostic accuracy (80, 61.5 and 84.5%, respectively) in the diagnosis of prostatic cancer. We believe that f/tPSA is not a definitive test for diagnosing prostatic cancer. Our observations on the behavior of percent free PSA in relation to prostatic carcinoma grading and staging and in the follow-up of carcinoma patients are interesting; however, further studies are needed to define the appropriate role of f/tPSA in patients with an established diagnosis of prostatic carcinoma and in the follow-up of patients with prostatic cancer.

Surgical pathology examination of radical prostatectomy specimens. Updated protocol based on the Italian TAP study

Between January 1996 and June 2000, 192 men with prostate cancer underwent radical retropubic prostatectomy (RP) and bilateral pelvic node dissection in 26 centers participating in the Italian randomized prospective TAP study. The reviewing pathologist evaluated 145 RP specimens. Seventy-five cases had not been treated with total androgen ablation before RP was performed, whereas 70 had been treated for three months. Whole-mount sectioning of the complete radical prostatectomy specimens was adopted in each center for accurately evaluating the pathological stage of prostate cancer and resection limit status. The results of this study suggest that total androgen ablation before RP is beneficial in men with clinical stage T2 because of the significant pathological down-staging and decrease in the number of positive margins in the RP specimens. On the basis of the experience acquired through the Italian TAP study and recent publications on prognostic factors in prostate cancer, the original practice protocol for examination of RP specimens removed from patients with carcinoma of the prostate glands was updated.

[Ultrasound-guided cryosurgery of the prostate: short- and long-term experience]

We have assessed 24 patients consecutively treated with cryosurgery and chosen according to the guidelines of the European Study Group of Urologic Cryosurgeons. Of the 24 patients (average age about 70, range 61-79), all were not considered candidates for radical prostatectomy, 9 (37%) were clinical stage cT2 N0M0, 15 (63%) cT3 N0M0 who had not received any prior treatment, except 1 patient (61 years old) who was treated with TCT and successive recurrence of the disease (cT2). Of the 24 chosen patients, 13 (55%) were over the age of 71, 11 (45%) had important factors of co-morbidity and an elevated risk of surgery (ASA 3). The average PSA was of 19.3 ng/ml (range 2.2-61). Gleason score was 2-5 in 9 cases, 6-7 in 14 and 8-10 in 1 case. In the follow-up, we evaluated serum PSA every 3 months and transrectal ultrasound and the echoguided prostatic biopsies at 6, 12 and 24 months. Post-operative complications included: ecchymosis and edema of external genitals (16/24), fever > 38 degrees C (1/24), sloughing syndrome (6/24), urinary tract infections (10/24) acute urine retention (1/24). In 2 cases, 6 months after treatment, a transrectal resection was carried out. After a follow-up at 6 months, the PSA was 0.4 ng/ml (range 0.1-0.9), in 1 case. In positive core biopsy out of 6 showed neoplastic cells with fibrous tissue; the patient had a PSA of 0.58 ng/ml. At 12 months there were 11 assessable patients. The average PSA was 0.3 ng/ml (range 0.1-0.9). At 24 months there were 4 assessable patients, 1 of 4 showed serum PSA level of 4 ng/ml and cancer in apical biopsy. Erectile dysfunction was assessed on 8 patients affective before surgery: 1 referred to sufficient erections at penetration (1/8, 12.5%). After removal of the catheter, 4 of the 20 patients suffered stress and urge incontinence with the use of 1 pad a day. In 1 case, 18 months from surgery, slight stress incontinence was found (1 pad/day). Cryoablation is an efficient method and is given to slight post-operative morbidity and no intra-operative mortality, also in patients with high risk for open surgery. Indications may be found in patients with the following conditions: older than 72 years, severe co-morbidity and high risk for surgery, neoplasia at high risk of progression, and disease recurrence after radiotherapy. Our case history is at the moment encouraging and a larger number of cases as well as longer follow-up are needed.

[Role of transrectal ultrasonography in the follow-up of patients treated with prostatic cryosurgery]

Cryosurgery of prostate is a minimally invasive treatment for localized cancer. Imaging techniques (transrectal ultrasound (TRUS) or magnetic resonance) have been proposed to evaluate tumor persistence/recurrence after cryosurgical treatment other than serum PSA and prostate biopsies. Actually, criteria to identify cancer after cryosurgical ablation are not well assessed. Aim of this study is to evaluate the clinical significance and role of TRUS in detecting tumor within the former prostate gland after cryoablation. We evaluated ultrasound (US) features and imaging, serum PSA and biopsies in 20 patients treated by cryosurgery at our Hospital with a mean follow-up of 18 months. Twenty patients (mean age 70 years, PSA 25.9 ng/ml, clinical stage: 10 T2 N0M0 and 10 T3 N0M0) were followed up for a mean of 16 months. Ultrasound findings (gland volume, capsule, hypoechoic area, post-voided urine volume, seminal vesicles) were correlated to PSA levels (every 3 months) and prostate biopsies (6, 12 and 24 months). All cases were evaluated by the same ultrasound scanner (Eidos, Hitachi-5-6.5 MHz) and by two operators. Prostate capsule was interrupted by hypo-hyperechoic areas in all cases. Transition zone was no more recognizable. Ultrasound findings showed in all cases hypoechoic areas, but US did not identified tumor recurrence in 2 patients. During follow-up, PSA below 0.5 ng/ml was recorded in 75% of cases. We detected tumor in 2 cases, respectively 12 and 18 months after cryosurgery: in the first case few residual cancer cells within fibrous tissue were found in 1 out of 6 biopsies at 6 months (PSA 0.58 ng/ml), in the second one, tumor with viable normal prostatic glands was found in one biopsy of the apex at 18 months (PSA 4.0 ng/ml). TRUS showed several anaechoic foci with necrotic tissue and coalescence of liquid areas in 2 patients (one developed acute urinary retention). Actually, serum PSA is the best marker in order to detect clinically significant tumor after cryosurgery. Hypoechoic areas and capsule interruptions observed by ultrasound imaging of prostate gland after cryosurgery are not correlated with tumor recurrence or tumor persistence. TRUS is only indicated for ultrasound-guided biopsies during follow-up and to confirm urologic complications.

Tunable supramolecular synthons and versatile, water-soluble building blocks for crystal engineering:

It is shown that the water-soluble dicarboxylic cationic acid [(eta5-C5H4COOH)2Co(III)]+ (1) is an extremely versatile building block for the construction of organometallic crystalline edifices. Removal of one proton from 1 leads to formation of the neutral zwitterion [(eta5-C5H4COOH)(eta5-C5H4COO)Co(III)] (2), while further deprotonation leads to formation of the dicarboxylate monoanion [(eta5-C5H4COO)2Co(III)]- (3). Compounds 1. 2 and 3 possess different hydrogen-bonding capacity and participate in a variety of hydrogen-bonding networks. The cationic form 1 has been characterised as its [PF6]- and Cl- salts 1-[PF6] and 1-Cl.H2O, as well as in its co-crystal with urea, 1-Cl.3(NH2)2CO, and with the zwitterionic form 2, [(eta5-CH4COOH)(eta5-C5H4COO)Co(III)][(eta5-C5H4COOH)2Co(III)]+[PF6]-, 2.1-[PF6]. The neutral zwitterion 2 behaves as a supramolecular crown ether: it encapsulates the alkali cations K+, Rb+ and Cs+ as well as the ammonium cation NH4+ in cages sustained by O-H...O and C-H...O hydrogen bonds to form co-crystalline salts of the type 2(2)-M[PF6] (M = K, Rb, Cs) and 2(2)-[NH4][PF6]. The deprotonated acid 3 has been characterised as its Cs+ salt, Cs+-3.3H2O.

Role of neoadjuvant treatment in clinically confined prostate cancer. Takeda NHT Italian Group

OBJECTIVE

This prospective, randomized, multicenter comparative trial studied the effect of neoadjuvant hormonal treatment (NHT) prior to radical, prostatectomy.

METHODS

Histopathologic tissue specimens were obtained from 91 consecutive patients (aged 60-70 years) who underwent a radical prostatectomy for stage B prostate adenocarcinoma. The patients had received NHT for three months. Specimens were compared with those from 48 age-matched control patients who underwent similar surgery for stage B disease without receiving preoperative therapy.

RESULTS

Treated tumors with an acinar pattern were distinguishable from the untreated tumors by neoplastic acini that appeared shrunken and areas of individual infiltrating tumor cells separated by an abundant interglandular connective tissue. The epithelial tumor cells had inconspicuous nucleoli, nuclear shrinkage, chromatin condensation and pyknosis, cytoplasmic clearing, and enlargement by coalescence of vacuoles and rupture of cell membranes. No mitotic figures were seen in any treated tumors.

CONCLUSIONS

Preliminary results show a benefit for patients receiving NHT in regard to the histologic indicators that we evaluated.

Leuprorelin 1-month depot as neoadjuvant therapy for prostate cancer. Takeda NHT Italian Group

In the last few years, the role of neoadjuvant hormonal treatment (NHT) prior to radical prostatectomy has been largely debated and investigated in randomized multicenter trials as well as in large single-institution studies. We have initiated a prospective randomized comparative trial with parallel groups in patients with clinically limited disease to contribute to the clarification of the possible role of NHT; to evaluate the efficacy of NHT with leuprolide plus cyproterone acetate in 'maintaining' the stage of the disease; to reduce the percentage of pathological overstaging, and mainly to accurately assess the pathological modifications induced by NHT. The present paper is an interim report of the results.

[Urinary NMP22 as a new marker in patients with transitional cell carcinoma]

To evaluate urinary NMP22 dosage as a marker of urothelial tumours, we have selected a group of 90 patients (85 males and 5 females, mean age 66 years) with clinical suspicion of transitional cell carcinoma (TCC), with microscopic or macroscopic hematuria, flank pain, urographic abnormalities and dysuria. All the patients have been evaluated by urinary cytology, renal and bladder ultrasound, cystoscopy. When a bladder tumour has been detected, bladder biopsies and, when required, I.V.P., CT or retrograde pyelography have been performed. A urine sample has been collected between midnight and noon; all samples from patients who were undergoing invasive procedures such as cystoscopy, were collected before or at least 5 days after the procedure. The test has been performed according to ELISA NMP22 (Matritech) technique; the test is specific for the nuclear matrix protein/nuclear mitotic apparatus protein expressed by cancer cells. When performing the test, 30 patients presented macroscopic hematuria. 22 patients resulted to have benign urinary tract conditions, 65 patients had TCC and 3 patients had a final evaluation suspicious for TCC. The NMP22 values were respectively 7.1 +/- 4.7 U/ml, 21.9 +/- 21.0 U/ml and 16 +/- 8.0 U/ml. From our study the sensitivity of the test is 67% (with a threshold value of 10 U/ml) and 55% (with a threshold value of 20 U/ml), while the urinary cytology resulted to have a sensitivity of 26% (p < 0.05). The sensitivity of the test in relation to staging was as follow: Tis 66% with a mean NMP22 value of 23.3 U/ml, Ta 26% with a mean NMP22 value of 13.2 U/ml, T1 100% with a mean NMP22 value of 40 U/ml, T2 73% with a mean NMP22 value of 36.4 U/ml. The specificity of the test was 100% with a threshold value of 20 U/ml. When considering a threshold value of 10 U/ml, the NMP22 test has a sensitivity higher than cytology, especially in low stage TCC. Macroscopic hematuria does not affect its sensitivity; the diagnostic efficacy of the test is not increased by the association of urinary cytology. It has an important role in the diagnosis of residual disease after TURB and in the follow-up evaluation of bladder cancer patients, since its dosage is not influenced by inflammatory conditions of the mucosa. We believe therefore that NMP22 is useful in clinical practice.

[Interstitial laser coagulation of the prostate in patients with prostatic hypertrophy: preliminary results with medium-term follow-up]

Although transurethral resection of the prostate (TURP) is the gold standard for treatment of BPH, a new, minimally invasive technique, called Interstitial Laser Coagulation (ILC), introduced by Muschter and Hofstetter, has been developed to treat BPH. ILC is base on the coagulation of prostatic tissue by means of diffused laser light using a diode laser system with a temperature feed-back (Indigo Medical 830e TM). We report our results in treating 20 patients with BPH and Bladder Outlet Obstruction (BOO), after a mean follow-up of 7 months. To define the indication for treatment and to monitor the success, urinary flow-rate (Omax), I-PSS symptoms score, residual urinary volume and prostate volume determined by ultrasound were recorded before treatment and after 3, 6, 12 months. Transurethrally, under spinal or regional anaesthesia, 2 or 3 insertions of the laser fibre in each prostatic lobe were performed beginning at the apex directly proximal to the bladder neck, made at 1 cm intervals, using a modified model Olympus cystoscope. After 6 months, Qmax increased from 6, 7 ml/sec to 11, 3 ml/sec; I-PSS score decreased from 18 to 8; residual urinary volume from 130 ml to 40 ml, prostate volume decreased from 60 to 48 ml. In selected cases, urodynamic evaluation was performed before and after treatment. Urodynamic findings were classified according Shafer diagram to grade B.O.O.: the score was 4 before treatment and 2 after 6 months. We observed UTI in 3 cases, retrograde ejaculation and acute urinary retention in 1 case, transitory irritative and obstructive syndrome in 8 cases after treatment. ILC is a simple, safe and effective treatment for BPH with significant improvements in both objective and subjective parameters. It is cheaper than others mini-invasive therapies and is able to treat any prostate volume, saving urethra and sexual function.

[Transurethral needle ablation (TUNA) in benign prostatic hypertrophy: 2-year follow-up]

In this study we have evaluated the effectiveness, safety and tolerability of TUNA in the long term follow-up. We have evaluated 24 patients, aged between 66 and 81 years (mean age 73, 4 yrs) with a mean prostatic volume of 57 ml (range 33-140 mls). Before treatment, urodynamic investigation (max flow rate), residual volume, PSA, IPSS and quality of life tests have been performed in all patients. After treatment, all the patient have been evaluated at 6, 12 and 24 months by the same parameters. Based on our experience, we can say that the results obtained after 24 months are similar to those observed 12 months after treatment, except a slight increase in IPSS and quality of life tests in patients older than 70 years, with a baseline maximal detrusorial pressure > 60 cm H2O, with a baseline residual urine > 100 cc and with a baseline quality of life = 5.

[Functional urination disorders in patients recovering in an intensive care unit for more than 30 days]

Patients in rest-homes, intensive care units, long hospitalization and dialysis and whoever stays in a hospital continuously or occasionally for long periods of time may run into the well-known and typical complications of prolonged hospitalization. We have studied the urologic aspect in all the cases of the Medical- Surgical Emergency Institute in the Hospital of Ancona (seated in Torrette), over the period 1990-96, in patients hospitalized for at least 30 days. All the patients were followed and studied with the same method, though taking into account their different pathological conditions. They were treated by the same medical and paramedical staff. The same antibiotic therapy and the same checkup were adopted for all of them. We have noticed that out of 122 patients the most frequent pathologies have been urinary infections (19%); while sepsis with different pathogenesis was recorded in 4% of the patients. The method of study applied during and after the hospitalization was used also in rehabilitation centres and included: urologic examination, rectal touch (in men), direct X-ray of the abdomen, ultrasound of the urinary tract, X-ray urography, if required; moreover urodynamic examination, MRI of encephalon and spinal marrow in patients with neurological lesions. The catheter was removed in all the patients and none of the following conditions were observed: vesical lithiasis, abscesses, fistulae in penoscrotal angle, urethrostenosis, injuries to renal emunctory. In conclusion we believe that the functional symptoms of minction--be they of obstructive or irritable nature--are not existent and that the urologic prognosis in long term patients in excellent, provided that prophylaxis is carried on against hospital urinary infections as their occurrence is very frequent and therapy is expensive. It can also be stated the patient hospitalized in ICU will not present damages to the urinary tract, even if he/she has been hospitalized because of injuries to the urinary tract, provided that the urologic tutoring, together with the action of the physician handling the Emergency, follow the rules for asepsis, the best biocompatible materials are use, infections are monitored, the extensions of cerebrospinal injuries are examined and therapeutic axioms, such as barren and clean intermittent catheterism, are finally adopted.

Serum markers for monitoring of prostatic carcinoma

BACKGROUND

Serum TPS (tissue polypeptide-specific antigen) has been observed to be characteristic of carcinoma proliferation, and increased levels of TPS seem to be closely related to tumor progression. In this study we wanted to evaluate the importance of the tumor-marker TPS in the diagnosis and follow-up of patients with prostatic carcinoma, and to compare it with prostate-specific antigen (PSA).

METHODS

We considered 39 patients with clinically confined disease, who underwent neoadjuvant hormonal therapy and thereafter radical prostatectomy, and 45 patients who did not undergo surgery and underwent hormonal adjuvant therapy alone. PSA and TPS were measured at the time of diagnosis and at regular intervals in the follow-up; TPS was measured in a control group of patients as well.

RESULTS

We were able to observe that, in untreated patients, PSA correlates with clinical stage, increasing with increasing tumor stage; a similar correlation was not observed when considering TPS. After androgen ablation we observed a decrease in PSA, but the serum values of TPS remained higher, suggesting that activity still exists inside the tumor. The evaluation of TPS appeared to be of particular interest in the follow-up after radical prostatectomy, especially in patients undergoing hormonal therapy; in fact, we were able to observe that relapse of the disease can be suspected early by the increase of TPS in hormonally treated patients.

CONCLUSIONS

We assert that TPS can add useful information on the state of neoplastic illness, especially in patients following adjuvant androgen-suppressive hormonal therapy, after radical prostatectomy; serial measurements of this marker could be useful in the early diagnosis of a relapse.
